Core Worlds

The Core Worlds of the Federacy are most of the worlds within one sector of Home, and all are on "this side of the rift."
Technology distribution is relatively consistent within the Core Worlds, with most significant settlements being T3. Though the Houses add some cultural (and political) flavoring, by and large, the culture is relatively homogenous and inwardly peaceful. Differences are more badges of individuality than reasons for disagreement, thanks again to a smoothly functioning Post Scarcity Economy.
